I use the same. In France one commercial name is "Carréponge". Which means "square sponge". One alf in each lung works fine -and colors are fun !
Descriptif produitYep exactly like that.
I then only use one in exhale, because whatever is in the inhale I can get into the exhale or clear out the OPV.
After a dive I allways VERY carefully taste the water in the pad to detect any salt form possible leaks. None so far, and no caustic either
